Application filed July 3. 1905. Serial No. 268227.

To (all whom, it may concern:

. it known that I, MAX M. Conn, a citizen oi the United States, residingin the city and coun of San Francisco and State of Caliave invented newand useful Imem its in Bookkeeping-Machines, of

pro v which the following is a specification.

My invention relates to a machine for bookkeeping or posting and to asystem of accounting, and especially to a machine for and a system ofposting items to a ledger-account and keeping the ledger accuratelybalanced at all times. i

Under present methods an immense amount of laber. is entailed on theotlice force of large .business houses to keep the various items ofsales and cash receipts properlypostand a still greater effort isnecessary at the end of each month to get a correct balance, commonlyknown as the trial'balance. The object of the present invention is toprovide a time and labor saving means which does away with copying orwriting by hand the amount of sales, credit memoranda, and cash itemsinto a ledger-account, and to provide a means for keeping the booksalways accurately balanced.

The invention consists of the parts and the construction and combinationof parts, as hereinafter more fully described and. claimed, havingreference to the accompanying drawings,in which- Figure 1 is a sideelevation of my apparatus. Fig. 2 is afro nt elevation of same. Fig. 3is a sectional view of the sprocket. Fig. 4

is a sectional View of three bars, showing the overlapping of theledger-sheets. Fig. 5 is a Fig. 6 is a perspective view of a removablebar or clamping-bar. Fig. 7 shows a modification of that shown inFig. 1.Fig. Sis a view looking from-the left of the drum shown in Fig. 7. Fig.9 represents the sheet of a loose-leaf ledger. Fig. 10 representsthesheet of the guide-strip. i

In Fig. 1-, which illustrates the form otm'achine. preferred where thereare several hundred accounts to be changed, A is a frame of suitablesize and design in which are suitably journaled a plurality of pairs ofsprocketwheels 2. The sprockets. are shown as journaled on arbors,leaving the space between the sprockets on thetwo sides within the frameentirely 0 en, so as not to interfere with the ledger-s eets, which areadapted to The slats of the carrier are be carried on suitable conveyingmeans ing over the sprockets.

The conveying means for the ledger-sheets, bills, statements, or thelike to be printed on consists of alternating-long and short bars orslats 3 4. The slots are perforated near their ends and are connected inendless carrier fashion by means of the endless wire cables .3, passingthrough the perforations in the be i A bar or slat 6 is made fast to thecable. e and forms a starting-point on the carrier, and all the otherbars or slats 3 4 are slidable on the cables in relation to the bar orslat When all the bars 3 4 are pushed around and pressed against oneside of the bar 6 and are in close contact with each other, there willbe a space of one or two inches, more or less, between the other side ofthe bar 6 and the last of the series of bars 3 01 l. This space (represented at 7) is for the purpose of allowing independent movement ofany of the movable barsB 4 to enable the sheets to be put into or takenout of the machine, as will be describe 1 shortly.

The teeth of the sprockets 2' are peculiar, in that they are partly cutaway to form outside iianges 8, against which flanges shorter bars orslats l abut and between which flanges or teeth the long bars or slatsengage. The purpose Ofcutting the to. this fashion is to accommodate thellui'S, which must-lie side by side, and to provide suitable guide meansagainst any pos. lo

pass

1 tne longitudinal movement of these carrier bars or slats.

It will be observed that by using long and short bars or slats 3 4 andcutting the teeth on the sprockets in the manner shown the bars can lieclose to one another, working with tachment of an adding-machine, as C,with which my machine is adapted to be used. supported be tween thesprockets on suitable guides c on the frame A. Each side'ot each bariscct out, as at 8, between the, ends of the b; equal approximately tothe length and thickness of the sheet which is to ,be posted onto.-These recesses or depressions on the sides of a bar correspondsubstantially in length to the length of the sheet tobe inserted, andtheir object is to allow the bars always to'be shoved up'snug againstone another irrespective of 1 this opening is moved the number of sheetsthat may be on the carrier. were not provided, the distance of any par-5 ticular movable bar from the bar 6' would vary according to the numberof sheets of paper included between said movable bar and the fixed bar.Thus if there were two hundred sheets of paper inserted between the rofixed bar and the succeeding two hundred movable bars or slats, and ifthe ag regated thickness of these sheets amounted to one inch, then thetwo hundredth movable bar or slat would be one inch farther removed fromthe fixed bar or slat than if there we're no sheets between said twohundredth bar and the fixed'bar. With my arrangement, however, withall-the bars shoved up against one another and against the fixed bar thedistance of the said two hundredth bar from the fixed bar remains alwaysthe same.

The bars 3 {i are all of uniform width-'say about a quarter of aninch,and equal to the distance between the lines of a sheet to be postedto.

of any suitable material, either wood or metal or celluloid or the like,and preferably provided with a suitable resilient surface of rubber orother material suitable for type- 0 face to impinge unon.

9 and 10 represent two metal strips or guides, which are fixed to theframe A and extend all around the carrier and project over and cover theopposite ends of the bars.

5 At some suitable point between the different pairs of sprockets, andpreferably at the front of the machine, as shown, these guides 9 10 arecut away to provide a suitable opening for the insertion of the sheets,which latter at all points in their travel except across this openingare adapted to be engaged at their ends by the guides 9 l0 and held inplace thereby.

B represents the sheet of a loose-leaf ledger, such as in common use,and having 'lines spaced from each other in exact correspondence withthe width of the bars 3 4. If desired, the sheet B may be creased onthese lines so as to be easily folded fiat over any movable bar and beclamped between the two adjacent bars when the three bars are shoved upinto contact with each other. By having a sheet creased, as at b, theinsertion of the sheets over and'between the barsis materiallyfacilitated, besides assisting in securing uniformity in the arrangementof the matter and figures designed to be type written on the sheet.

To insert the sheets into the machine, the

carrier is turned to bring the fixedbar 6 into the ,open space '7between the ends of the guides 9 10. Theseries of movable bars 3 4having been suitably separated from one side of the fixed bar 6, asindicated by the opening 7, the bar 3 or 4 on the other side of If somesuch means as the recesses 8- der the spring ends sheet after sheet isfolded -over a 'bar, and the-bars move upone be- The various bars orslats may the they just overlap art way across the opening, so that afol ed sheet B can be made to straddle this bar. This barwith its sheetis moved up against the bar 6 and the carrier turned-by hand to move theends of the bar and-the outer edges ofthe sheet uner the guides 9 10. Asucceeding movable I bar is then advanced into the open space and asheet folded over it .and moved up against the first bar and its sheetand yi mder the guides 9 10.1 Thus or bent and laid hind the other untilall the sheets representing all the accounts in the ledger to be;

changed at that time are inserted. The inclosed space 7 thenremainingbetween-tht bars is closed by means of a series of removablebars 12, which have" the notches 13, allowing these blank spacer-bars tobe hooked 8 5 over the cables 5. If the space 7 is two' inches in width,and the uniform widthof all the bars is a quarter of an inch, therewould be eight of these spacer-bars insertedinto the space 7, serving tokeep all, the bars 96 pressed tightly against each other and against thefixed bar 6. The guide-straps 9 10 are so arranged that the narrowexposed stripsof the sheets and prevent the sheets falling out frombetween the clam -bars 3 4 and also serve the same function in regard tothe spacing-strips 12.- When all the sheets are clamped in the frame,there is only an amount of each sheet showing that corresponds to 0b thewidth of a clamp-bar and to the space between the guides 9 10. Havingthus provided suitable means for holding a number of sheets and forsimultaneously ex osi'ng a limited portion only of each sheet, am able1o 5 by means of suitable connections with an adding-machine to postdirectly and mechanically to each sheet the entry whichheretofore hasgenerally been carried for ward into the ledger by laboriously Writingno in by hand.

In the resent instance and for conven- -ience of 11 ustration I haveshown my apparatus used in conjunction with a Burrou hs adding-machine;but it is obvious that ot er 1 r 5 machines are applicable in the samecombination. Y

C represents an adding-machine having the usual type mechanism'c, whichis adapted to be projected outward on the actuation of the 1 2'0 lever14 to the left to print upon a strip of paper held in suitable relationto the type. 1' simply remove the paper-holding roller and carriage ofthe ordinary Burroughs machine,

and instead of printing onto a se arate strip 12 5 of paper I rintdirectly onto-the s eets whion are carrie by the clamp-bars 3 4.

The adding-machine lsmounted on a car riage 15, Which is provided withrollers 16, running in grooves which extend transversely 1 o of the basea of the frame This bas ever the lever 14 on the adding-machine is areso arranged and assembled that a clampwith the type-face of the printinmechantype outward and make retracted,

enough wider than the macline'for hol the sheets to permit theadding-machine to be moved clear to one side, so as to expose a l theprinted matter on the exposed portion of the sheets on the carrierandallow the sheets to be easily placed on or taken oh of the carrier. Afeather-shaft 17 is supported on the base in suitable relation to thecarrier mech anism and to the adding-machine and carries a ratchet 18,which is siidable thereon and turnable'therewith. This ratchet issupported in the crotch of a forked lever 19, which is fulcrumed on theshaft 17 and slidable on the shaft, but turnable independently of theshaft. This lever 19 carries a pawl 20, adapted to engage with theratchet to turn it and the shaft 17 when the lever 19 is moved in oneoirection and to ride free over the ratchet when the lever swings in theother direction. This lever 19 is made to move back and forth with theadding-machine C and to have its outer end always disposed in the pathof a cam 21 on the operating-lever 14 of theadding-machine. 1 hismovement of the lever with the adding-machine is insured by means of acurved bracket 22, secured to the addin -machine and embracing the leverwithout interfering with its oscillating movement.

One end of the shaft 17, and preferably that end toward which theadding-machine is moved when it is desired to get at the carrier, isprovided with a pinion 23, engaging a large gear 24 on the shaft of oneof the sprock ets 2. Hence it will be observed that whenthrown forwardto cause the cam 21 to rock the lever 19 the ratchet 18 will move onestep, turning the shaft 1? and operating through the gears 23 24 toadvance the carrier one bar-space. It is understood that the parts barwill always be brought at each actuation of the lever 19 into exact andproper relation ism c.

In making an entry, assuming the addingmachinet'o be moved so as tobring the typeface opposite the proper place where it is desired toprint upon the sheets, the appropriate keys 25 on the adding-machine aredepressed. Pulling the lever 14 to the left operates in the usualmanner, not necessary 1 here to be shown or described, to throw the theproper imprint on the particular sheet on the particular bar which atthat moment happens to be in the ath of the t "pe. Throwing the lever 14ack to normafposition, which is the position indicated in Fig. 1, theprinting devices are which will permit the carrier to move. Before,however, depressing the keys 25;-f0r the next entry the levee 14 isrocked forward or to the right, tocause the cam 21 to depress the lever19 and advance e carrier one bar-space and bring the the printoewhereupon the next ent y may depressing the appropriam keys the lever 14to the left, and so on th whole series. in order to afford some sort ofa guide for A ator that he may know 1 1st which particular sheet or baris being printed on at particular time, I have numbered the bars in. acertain systematic manner which will permit him, by looking at a slot 26in a idestrip 9, to determine just which. bar is the path of theprinting devices. For this purpose all the movable bars at one end arenumbered consecutively from one side of the fixed bar 8 around towardthe other side of this iixr-d bar. These numbers appear through the slot26. The slot 26 is disposed at a known distance from the line of type,which may be said to be six inches,'measured around on the curve of thecarrier. Hence if all the clamp-bars are one-quarter of an inch thickthere would intervene twenty-four bars between the slot 26 and theprinting devices. Consequently the twenty-fourth bar from the slot wouldalways be the bar which. carries the sheet immediately opposite theprinting devices.- Starting with number 1, showing through the slot 26,the twenty-fourth barlrom this slot, measured in the correct direction,would be numbered 1 These latter numbers would be placed on the ends ofthe bars opposite to or to the right of those numbers which appear inthe slots 26, and the said latter numbers would run consecutively, sothat whatever number appears in slot 26, it would be known that a barbeariiig exactly the same number is directly opposite to the printingdevices.

in the practical ap lication of my invention I proceed as fol ows: Thevarious entries are listed on a regular adding-machine in the usualfashion on narrow slips of paper, such as shown at D. There is a listfor sales, a list for cash credits, randa, a list for journal entries,and a list for any kind of pntries that are to be transferred or postedinto the ledger or other permanent record. if desired, these sales maybe made on strips of different colored paper to assist in the readyrecognition of the several entries.

These lists are verified and must be absolutely correct. They should bemade on strips that'are consecutively numbered correspondingly with thenumbers on the bars of the clam ing-machine. If desired, the

numbers can be placed on the sli s with the' aid of a numbering-machine.lifter these slips are prepared the ledger sheets or cards that are tobe posted are taken from their binders or files and dated and numberedwith a combined dating and numbering machine, which also prints theclasses of entries, (as

M. for merchandise, C. for cash, &c.) The number on these ledger-sheetscorrespond LII ' prepared list is also of this sheet appears same wayaround the opening space 7 with the numbers appearing on the strip Doppositethe amount to ticul'ar account. I

W hen the led er-sheets have been dated and numbered, t iey are placedin numerical order in the bookkeeping-machine, and the l laced in themachine with oneiend clamped etween two of the bars '3 or 4, andunderthe guide-strip 9 and with l number-PT on the list corresponding withleft of the machine viewable through the slot 26. The ledger-sheets,however, are placed in the machine in consecutive order corres ondingwith the numbers on the right of t e machine. While the numbers on thetwo ends of the bars run the number 1 at the hers on the opposite endsof any one'bar will f differ from each other, as we have seen, by

just the numbers of bars that there are between slots 26 and theprinting device. The list D when inserted into the machine s aces on thelist. so correspond with the s ats on the carrier that the movement ofthe travels under the guide 9, and the number of new ledger-sheet nfront of the printingwheel, a number corresponding to the number throughthe slot 26. The slot 26 is also of such shape and sizethat the'amountwhich is ,to be transferred onto the ledger-sheet appears through thisslot. All that is then necessary for the operator to do is'to' depressthe proper keys and pull the lever, which will print the amount to beposted on theproper sheet. Pushing the lever in the opplosite-directionadvances the carrier and t e guide-slip D, bringing the next sheet intocorrect position with the printingwheel of the adding-machine andexposing the succeeding number and amount in the slot 26, which isinplain view of the operator. The same operation is repeated until theentire list is posted and the total is shown in the slot. The total-keyis then depressed on the adding-machine and the amount printed on atotal or balance sheet carried by the carrier and which may be kept inthe back of thc ledger. After all the sheets have been properly postedthe adding-machine is moved to one side and the bar 6 brought intobetween the ends of the guides 9 10. The spacer-bars are removed and thesheets are then taken out one ata time, beginning with the sheet whichwas inserted last into the machine. This process of taking out thesheets brings the slats 3 4 into be posted to that parthe carrier, thetwo numcarrier each timeit is advanced to bring a '1 their originalposition relative to the bar 6 and with the opening 7 on the same sideof l the bar 6, so that the movable bar which is just across thisopening nearest to bar 6 will be numbered 1 at its rightend.

W here a great many accounts are handled, it is preferable to groupthem, using a total or be ance sheet after each group, so that aseparate balance or total may bekept foreach grou In case accounts arekept in alphabet-ica order a total or balance sheet may be used aftereach letter and proved up separately in the manner above described.

Where accounts are ke t in geographical arrangement, a total or ba ancesheet may be used after each town, country', or State, as may berequired. v

This system insures absolute accuracy,

reatly reduces the amount of labor in an ofce, and allows the ofiiceworkto be kept up to date.

Where the ledger-sheets are ruled into separate entry-columns,(indicated at' 27,) tue base a may have a series of correspondinggraduatio'ns' 28', and the adding-machine may be provided with a pointer29.. The pointer 29 and the 'graduations'28 would serve to indicate tothe -o erator when he has moved his adding-machine into .properjuxtaposition with a particular column in which the entries are to bemade on the ledger-sheet.

my method of bookkeeping the acthere being a chance of an error in theoriginal entry, as well as a chance for an error in transferring theoriginal entry to the ledger. This doubt is now eliminated.

This system can be used in all operations requiring the transfer oforiginal entries to permanent or classified records, embraces allposting, such as charges, credit memoranda, cash entries, stock-records,and the like.

The machine. can also be used for making out bills and statements.

In Fig. 7 I have shown my invention which is adapted more particularlyfor use where there are only a limited number of changes each day to bemade. In this case I use the same idea of an endless carrier withclamp-bars, in combination with an adding-machine but instead of aflexible carrier passing over sprocket-wheels I em ploy a cylinder, asA, mounted to revolve upon a suitable support and arranged in properrelation to a shiftable adding-machine C.

The cylinder is composed of two heads having annular flanges 30 on theirinner sides, on which the clampbars 3i are slidable in relation to a bar6. which is made fast to a modification of r held into position amechanism similar to that described in connection with Fig. 1.
